Hadith 5501

(حديث مرفوع) حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ ، حَدَّثَنَا شُعْبَةُ ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ ، كُنْتُ مَعَ ابْنِ عُمَرَ أَنَا وَرَجُلٌ آخَرُ ، فَجَاءَ رَجُلٌ ، فَقَالَ ابْنُ عُمَرَ : اسْتَأْخِرَا ، فَإِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ : " إِذَا كَانُوا ثَلَاثَةً فَلَا يَتَنَاجَى اثْنَانِ دُونَ وَاحِدٍ " .
Abdullah bin Dinar (may Allah have mercy on him) says that once I and another man were with Sayyiduna Ibn Umar (may Allah be pleased with them). A man came, so Sayyiduna Ibn Umar (may Allah be pleased with them) said to both of us: "Move back a little, because the Prophet (peace and blessings be upon him) said: If there are three people, then two should not whisper to each other leaving the third one out."
